Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figures 1 to 6 As shown, the utility model provides a river water quality detection sampling device, including an open barrel 1, an installation barrel 2 is movably connected inside the open barrel 1, a blocking disk 4 is fixedly connected to the bottom end of the installation barrel 2, an adjusting barrel 3 is movably connected inside the installation barrel 2, the bottom end of the adjusting barrel 3 is movably connected to the blocking disk 4, a plurality of small holes 13 are opened on the outer surfaces of the installation barrel 2 and the adjusting barrel 3, and a plurality of filtering holes 12 are opened on the surface of the adjusting barrel 3.
[0023] The above scheme is adopted: first, the regulating barrel 3 is rotated according to the river conditions, so that the small holes 13 or the filter holes 12 inside the regulating barrel 3 are fitted with the small holes 13 on the surface of the mounting barrel 2, and then the open barrel 1 is placed below the horizontal surface of the river when the small holes 13 are completely covered, so that the sampled river water is separated from the horizontal surface to prevent larger impurities on the horizontal surface from clogging the small holes 13 or the filter holes 12, and then the blocking disk 4 is pushed downward to allow the river water filtered by the small holes 13 or the filter holes 12 to enter the interior of the regulating barrel 3, so as to carry out sampling.
[0024] like Figures 1 to 6 As shown, the end face of the blocking disk 4 is fixedly connected with a number of adjustment plates 5 at equal angles in a ring shape, the inner side of the adjustment plate 5 is movably connected to the open barrel 1, and a number of connecting blocks 16 are provided at the end of the adjustment plate 5 away from the blocking disk 4, and the two ends of the connecting block 16 are fixedly connected to the side adjacent to the adjustment plate 5, and the contact surface between the mounting barrel 2 and the adjustment barrel 3 is set to be smooth.
[0025] The above solution is adopted: by setting the connecting block 16, the adjusting plate 5 is moved synchronously, so that the blocking disk 4 moves to open the opening barrel 1, and the contact surface between the mounting barrel 2 and the adjusting barrel 3 is set to be smooth to reduce the friction and make the structure run more stably.
[0026] like Figures 1 to 2As shown, a fixing ring 14 is provided on the outer surface of the open barrel 1, and the fixing ring 14 is fixedly connected to the open barrel 1. A threaded spring is provided above the connecting block 16, and the connecting block 16 is elastically connected to the fixing ring 14 through the threaded spring.
[0027] The above solution is adopted: by providing the fixing ring 14, the limiting block 7 moved away from the fixing ring 14 is pulled back by the elastic force of the threaded spring, thereby being reset.
[0028] like Figure 1 As shown, the outer surfaces of the two adjustment plates 5 are fixedly connected with a fixed block 6, the upper end of the open barrel 1 is fixedly installed with a limit block 7, a limit handle 8 is provided above the open barrel 1, and the bottom end of the limit handle 8 passes through the limit block 7 and is fixedly connected to the fixed block 6, a push handle 9 is provided above the adjustment barrel 3, and the push handle 9 passes through the limit handle 8 and is fixedly connected to the adjustment barrel 3.
[0029] Adopt the above solution: push the push handle 9 to move toward the regulating barrel 3, so that the limit handle 8 drives the regulating plate 5 to open the opening barrel 1, so that river water can enter the interior of the regulating barrel 3 for sampling.
[0030] like Figure 2 and Figure 6 As shown, the upper end of the adjusting barrel 3 is fixedly connected with a clamping ring 15, and the adjusting barrel 3 is movably clamped with the mounting barrel 2 through the clamping ring 15. The end faces of the adjusting barrel 3, the adjusting rod 11 and the clamping ring 15 are each provided with two mutually symmetrical adjusting grooves 10.
[0031] The above solution is adopted: the adjusting barrel 3 and the mounting barrel 2 are clamped together by the clamping ring 15, so as to limit the height of the adjusting barrel 3 without affecting the rotation of the adjusting barrel 3.
[0032] like Figure 2 and Figure 6 As shown, the adjusting slot 10 is movably connected to the adjusting rod 11, and an annular spring is provided on the outside of the adjusting rod 11. The adjusting rod 11 is elastically connected to the adjusting barrel 3 through the annular spring, and the adjusting slot 10 and the adjusting rod 11 are consistent in size.
[0033] The above solution is adopted: by setting the mutual cooperation between the adjusting rod 11 and the adjusting slot 10, the adjusting rod 11 can limit the adjusting barrel 3 to prevent the adjusted adjusting barrel 3 from rotating, and setting the adjusting slot 10 and the adjusting rod 11 to be consistent in size to enhance the limiting effect of the adjusting rod 11 when inserted into the adjusting slot 10.
[0034] like Figure 2 and Figure 4 As shown, the filter holes 12 are arranged in the middle of the small holes 13 , and the spacing between the filter holes 12 is consistent with that of the small holes 13 .
[0035] The above solution is adopted: by arranging the mutual cooperation between the small holes 13, the water inlet diameters of the filter holes 12 and the small holes 13 do not affect each other when adjusting, making the structure run more stably.
[0036] The working principle and usage process of the present invention are as follows: when in use, first manually pull up the adjusting rod 11 to rotate the adjusting barrel 3 to drive the filter hole 12 or the small hole 13 to adjust. After the adjustment is completed, release the adjusting rod 11 and clamp the adjusting rod 11 inside the adjusting groove 10. Then pick up the limiting handle 8 to move the lower part of the open barrel 1 to the horizontal plane, and immerse the open barrel 1 in the river, so as to prevent the algae and larger impurities on the horizontal surface from contacting the filter hole 12 or the small hole 13 to block them. Next, press the pushing handle 9 to open the bottom of the open barrel 1, so that the river water passes through the small hole 13 or the filter hole 12 to filter the smaller impurities inside the river, and let the filtered river water enter the interior of the regulating barrel 3. When the required amount of water is collected, release the pushing handle 9 to allow the blocking disk 4 to move toward the limiting block 7, thereby covering the open barrel 1 to prevent water from flowing out of the regulating barrel 3. Then take the open barrel 1 out of the river, thereby completing the water quality sampling.
